to keep them warm, because chickens are natural incubaters
The term is Brooding
A hen past her prime laying years can and will still brood. Even if she lays no eggs herself she will sit there and collect eggs laid nearby.
Chickens do not get pregnant. Rather, they become broody and sit on their nest of eggs for at least 21 days to hatch baby chicks.
A broody chicken is when a hen decides to sit on her eggs... even if there is no rooster around, and even if the eggs belong to a bunch of random chickens on the flock... they will just sit on the eggs hoping to hatch them out, i guess.
Every single breed of hen (even mix) will sit on their eggs when they feel like they want chickens. One of the hens that brood alot are brahma hens.
No, absolutely not. Hens sit on their eggs until they hatch. They actually nestle their feathers above and around the eggs and keep them warm, but people say they are sitting or setting on their eggs.
No, a rooster produces sperm as do most males
yes, they do. it keeps the egg warm for the time being.
Yes they are more then fine, It mearly means the eggs are not fertilised and when the chickens become clucky and sit on the eggs they cannot incubate abd develop however if you were planning on breeding a rooster is essential.
It depends on the chicken. Some will sit and then gradually get more and more eggs. Chickens in all don't have a "limit" of eggs they will sit. Often a hen will go broody without sitting on any eggs. Some hens have sat on twenty eggs but it can be hard for them. Sometimes one egg. But on average and for an average chicken, it would be around a dozen.
Well to begin with, the turtle digs a hole and lays her eggs inside it. Unlike chickens and birds, turtles dont sit on their eggs to keep them warm, the sand does it for them. BTW Incubate: Sit on eggs in order to keep them warm and bring them to hatching OR Keep eggs at a suitable temperature in order for them to develop.
They have an instinct that makes them sit on them to keep them warm, and they protect them, so they probably do know in some way that the eggs are going to hatch into chicks.
